Troubleshooting Tip: You can decide how many calibration points you use (one, two or three points). The meter automatically detects the calibration solution used. The pH 7.00 solution must always be used as the first calibration point. The meter has a self-diagnosis function. "Er1" is displayed: when the reading exceeds the detectable range of the meter. "Er2" is displayed: the measurement was not stable when you pressed [Cal]. Wait for [Smiley] when measuring, before pressing [Cal]
NOTE: If you find white crystals inside or outside the electrode cap, this is completely normal. It is the 3M KCl that crystallizes over time. Simply rinse it and use the gauge as usual
Large LCD displays pH, temperature and calibration status
Easy calibration with automatic buffer detection
Complete set including calibration solutions, batteries and lanyard in a handy carry case
Automatic temperature compensation (ATC) (in the range 0-50°C)
ATTENTION: water droplets are added during production to maintain the moisture of the electrode. A damp electrode cap does not mean that the product has already been used

Widely used: pH test can measure in swimming pools, salt water pools, hot tubs, SPAs, aquariums, aquacultures, the pH meter can measure the EC and pH value of hydroponics. TDS and pH meters measure liquids such as permeate water, pool water, drinking water, tap water, irrigation water, pond water, garden water, coffee, fruit juice, brewed wine and beer
User-friendly design: the backlight ensures that you can use the product in dimly lit working environments. With the HOLD/TEMP button, you can record the reading, and the backlight turns off within 30 seconds. Press any button to turn on the backlight again
EASY CALIBRATION Supports automatic 3 point calibration and can easily achieve automatic calibration at 4.01, 6.86 and 9.18 according to the user manual. Don't worry about the calibration solution (equipped with a calibration package). The device has been factory calibrated and is ready to use when the device is received
Automatic temperature compensation: the pH meter does not need to pay attention to the temperature of the test liquid; this device can accurately measure sample values within the temperature range of 0 °C - 60 °C (32 °F-140 °F), causing the problem of inaccuracy due to liquid temperature changes. Whether in winter or summer, you can get accurate values
5-in-1 pH meter: a digital water tester drinking water can measure pH, salinity, EC, TDS and temperature; simply press the (MODE/CAL) button to switch between pH, salinity, EC and TDS and read values. Long press the HOLD/TEMP button to switch between the units temperature and Celsius. Meets the requirements for regular, daily monitoring of water quality and allows you to be informed about the situation of water quality at any time
